The fourth proportional to 4,6,8 is
If A:B=3:2 and B:C=3:5, then A:B:C is
If a/3=b/4=c/7, then a+b+c/c is
a/ 3 = b/ 4 = c/7
a/c = 3/ 7 ; b/ c = 4/7
(a+b+c) / c ⇒ a/ c+ b/ c + 1
⇒ 3/7 + 4/7+ 1
⇒ 1 + 1
⇒ 2

If A = B/2 = C/5, then A:B:C is
The third proportional to 12,18 is
Let the third proportion be x
12 : 18 = 18 : x
x = 18*(18/12)
x = 18*(3/2)
x = 54/2
x = 27
